Viral video: What is a Leap Year?

Happy Leap Day! We all learned about why we have Leap Years back in school, but that doesn't mean we committed it to memory, especially because we only have to think about it every four years.

The YouTube channel CGPGrey often breaks down subjects into quick, yet poorly illustrated, explanations and the channel's explanation of Leap Years has gotten popular in the past 24 hours, getting more than 200,000 views in that time span alone.

What do you think of the speedy review? Does it make you appreciate your extra day any more?
